First, I have no idea about any "atheist lists", but it seems as though you're trying to stop the discussion by comparing my point with that of unbelievers.
Just asking you to pony up with the 'proof'. If the discussion stopped because of it then that would be fine by me, it would show that you didn't have the 'proof'.
A good hope, and one that is well founded.
Let's look at a couple for starters.
1) Sirach 3:3, 30 contradicts Leviticus 17:11 by stating alms can be an atonement for sin, when Leviticus states atonement is by blood.
#1) I see, so accessing the means of atonement by an act of faith, repentance, and mercy is a bad thing? "
For the life of the flesh is in the blood; and I have given it for you upon the altar to make atonement for your souls; for it is the blood that makes atonement, by reason of the life". Think of it, if faith and repentance can access the sacrifice of Christ maybe alms as an act of mercy, repentance, and faith can too. Consider the story of the unforgiving steward.
2) Tobit 12:9 states that alms deliver from death and purge sin, which is a contradiction to 1 John 1:7 which states that only Jesus blood can do that.
#2) See reply #1 above and consider that accessing the sacrifice of Christ on the cross is the means by which sins are purged.
If we say we have fellowship with him while we walk in darkness, we lie and do not live according to the truth; but if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus his Son cleanses us from all sin. (1 John 1:6-7)
An act of mercy in giving alms seems like it might be walking in the light,
He looked up and saw the rich putting their gifts into the treasury; and he saw a poor widow put in two copper coins. And he said, "Truly I tell you, this poor widow has put in more than all of them; for they all contributed out of their abundance, but she out of her poverty put in all the living that she had." (Luke 21:1-4)
It isn't how much alms one gives but that one gives out of a good motive is what counts. As the scripture says,
Then the angel called the two of them privately and said to them: "Praise God and give thanks to him; exalt him and give thanks to him in the presence of all the living for what he has done for you. It is good to praise God and to exalt his name, worthily declaring the works of God. Do not be slow to give him thanks. It is good to guard the secret of a king, but gloriously to reveal the works of God. Do good, and evil will not overtake you. Prayer is good when accompanied by fasting, almsgiving, and righteousness. A little with righteousness is better than much with wrongdoing. It is better to give alms than to treasure up gold. For almsgiving delivers from death, and it will purge away every sin. Those who perform deeds of charity and of righteousness will have fullness of life; but those who commit sin are the enemies of their own lives. (Tobit 12:6-10)
The motive in the story of Tobit is faith, mercy, and humble repentance.
3) Wisdom 8:19,20 claims that one can be "undefiled" (sinless) yet Romans 3:10, and Romans 5:18, 19 say the exact opposite.
#3) The passage in Wisdom, in the words of Solomon the King, says no more than that Solomon was born with generous gifts from God, a good disposition, a healthy and undefiled body, and intelligence. The passage does not claim sinlessness.
Having meditated on all this, and having come to the conclusion that immortality resides in kinship with Wisdom, noble contentment in her friendship, inexhaustible riches in her activities, understanding in cultivating her society, and renown in conversing with her, I went all ways, seeking how to get her. I was a boy of happy disposition, I had received a good soul as my lot, or rather, being good, I had entered an undefiled body; but, realising that I could never possess Wisdom unless God gave her to me, -a sign of intelligence in itself, to know in whose gift she lay -- I prayed to the Lord and entreated him, and with all my heart I said: <Then follows a long prayer asking for wisdom>(Wisdom 8:17-21)
4) Sirach 12:4-7 says to not help the sinner, to "withhold bread" and such, yet that directly contradicts Luke 6:27,30, Romans 12:20, and Proverbs 25:21.
#4) Sirach 11:29-12:7 is a passage about choosing the right friends written by a father for his son. It says,
Sirach 11:29-12:7 Do not bring everyone home with you, for many are the traps of the crafty. (30) Like a captive partridge in a cage, so is the heart of the proud: like a spy he watches for your downfall, (31) ever on the look-out, turning good into bad and finding fault with what is praiseworthy. (32) A hearthful of glowing coals starts from a single spark, and the sinner lurks for the chance to spill blood. (33) Beware of a scoundrel and his evil contrivances, in case he puts a smear on you for ever. (34) Give a home to a stranger and he will start trouble and estrange you from your own family. (12:1) If you mean to do a kindness, choose the right person, then your good deeds will not be wasted. (2) Do good to someone devout, and you will be rewarded, if not by that person, then certainly by the Most High. (3) No good will come to one who persists in evil, or who refuses to give alms. (4) Give to the devout, do not go to the help of a sinner. (5) Do good to the humble, give nothing to the godless. Refuse him bread, do not give him any, it might make him stronger than you are; then you would be repaid evil twice over for all the good you had done him. (6) For the Most High himself detests sinners, and will repay the wicked with what they deserve. (7) Give to the good, and do not go to the help of a sinner.
It is good advice. God himself says he will judge the wicked and condemn them. But if you are concerned that the passage speaks against showing mercy to repentant sinners or to those who are downtrodden then you are mistaken. I highlighted the words that speak to that issue in the passage and I underlined the words that capture the essence of the wicked in their determination to persist in evil.
